Embodiment Construction

[0059] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0060] Each display panel can have multiple different display luminances. The luminous intensity nit value of the display panel is different under different display luminances. Usually, there are 0 to 255 gray scales under each display luminance, and the gray scale brightness values ​​corresponding to different gray scales are different. . example, figure 1 is a schematic diagram of the gamma curve corresponding to different display brightness, such as figure 1 As shown, the abscissa represents the gray scale of the pixel (referred to as gray scale for short), and the ordinate represents the brightness value of the gray scale. The display brightness corresponding to the 11 gamma curves in the figure is 20 nits, 30 nits, 40 nits, 50 nits, 60...

Abstract

The invention discloses a gamma correction method and device, a display device and a computer storage medium, belonging to the technical field of display. The method comprises the following steps: acquiring measurement data of a sample display panel, wherein the measurement data is used for recording at least one display brightness and compensating parameters corresponding to a to-be-compensated gamma curve under each display brightness; acquiring a gamma curve under each display brightness in at least one display brightness of each to-be-corrected display panel; and respectively compensatingthe gamma curve under each display brightness by virtue of the corresponding compensating parameters of the gamma curve under each display brightness in the measurement data until a gamma value corresponding to each compensated gamma curve is in a standard error range, wherein the to-be-corrected display panels and the sample display panel are produced in the same batch. The gamma correction method can solve the problems that the consumed time of a gamma correction process is relatively long, and the gamma correction efficiency is relatively low in relevant techniques.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gamma correction method and device, a display device, and a computer storage medium. Background technique [0002] With the development of display technology, Organic Light Emitting Diode (OLED), as a current-mode light-emitting device, is increasingly used in In the field of high-performance display. Due to the self-luminous characteristics of OLED products, gamma correction needs to be performed on each OLED product during the production process to ensure the optical effect of OLED products. The gamma correction refers to adjusting the gamma curve so that the adjusted gamma curve meets the requirements of the standard gamma curve. [0003] For OLED products with completed structures, the gamma curves under multiple display luminances will shift, so in the related art it is necessary to adjust the gamma curves under multiple display luminances. There are multiple g...
